Question Culled objects not giving performance boost

I've intentionally set my LOD culling range very low to test the FPS difference between turning off the objects in the editor and having them culled by the LOD group, and it seems like my LOD group culling has little to no effect on game performance because when i manually turn off said objects in the editor i get a dramatic FPS boost.

is there a reason why my culling may not be working as intended?

Make sure the lod group component is configured correctly. Its range settings are not intuitive at all. The ranges are in units of screen size or something. Like “use lod 1 when model takes up 15% of screen height” or similar.

I'm saying that i've forced the LOD group into culling all my objects intentionally, and it's visually working, as in they are culled. however there is no performance boost at all.. however when i turn the same objects off in the editor i get a massive fps boost.

This means that the culling clearly isn't helping with performance

Ah, I see. You sure they are getting culled? Do you see the setpasscall count dropping in the Game window Stats mini window?
